Re: [PATCH 1/1] fat: improve sync performance by grouping writes in fat_mirror_bhs [really unmangled]

Based on some rather off-the cuff bench marking I've done I get around
a 5 to 10% performance improve over the stock 2.6.18.1 performance. As
the saying goes, there are lies, damn lies, and bench marks, so YMMV.

So how much is performance improved?
